Before you choose
No preference panel appears during the opening film. After you skip the film or the skip option has completely disappeared from the screen, a preference icon appears; select it to open the panel. Google Analytics measurement and analytics cookies are enabled from your first visit, before you make a choice. Page views, technical session and usage information are sent to Google, together with your IP address and browser/device information. You can turn measurement off in the preference panel.
Measurement and advertising preferences
Google Analytics uses cookies to measure page views by default. If you turn measurement off, new page-view events stop, Analytics cookies are removed and Analytics measurement will not start on subsequent page loads. An already loaded tag may still send technical consent signals. We send page-view events to Google Analytics, rather than separate Analytics events for watching the film or submitting an application. Google Analytics may also process technical session and usage signals. We use Google Ads and Meta Pixel to measure advertising performance, successful contact requests and ATLAS beta applications, and to use visit information for ads relevant to your interests, including on Facebook and Instagram. Advertising is on by default and can be turned off separately from measurement. Turning advertising off stops new application advertising events and removes the site's Google Ads and Meta cookies. An already loaded Google tag may still send technical consent signals. This site setting does not delete cookies on Meta's own domains.
Closing the panel leaves your existing settings unchanged. Measurement and advertising preferences are on by default; previous refusals are preserved. “Reject all” turns both preferences off. In “Preferences”, you can change them separately.
Application measurement
Conversion events are sent only after the server confirms a successful submission. These events do not include your name, email address, telephone number or message; they use the submission type and a random transaction identifier. Meta receives one page-view event per actual page load and the application type and a random transaction identifier after a successful submission. Google and Meta may process IP address, visited page address, browser and device information. Enhanced matching and Meta's automatic form events are not used.
